Kann ich binden, um Inhalte aus den im Vorlagen verschachtelten Kontrollen zu verwenden?

Question

Ich möchte das verwenden System.Windows.Controls.DocumentViewer zu sehen a FixedDocument Ich habe aus einer PDF -Datei mithilfe der Datei erstellt TallComponents.PDF.Rasterizer. Dies funktioniert jedoch, ich möchte jedoch einige der von den angezeigten Symbolleistentasten deaktivieren oder entfernen DocumentViewer Kontrolle. Ich benutze die Vorlage Exmaple von hier.

<Style x:Key="{x:Type DocumentViewer}"
       TargetType="{x:Type DocumentViewer}">

          Value="{x:Null}" />
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type DocumentViewer}">
        <Border BorderThickness="{TemplateBinding BorderThickness}"
                BorderBrush="{TemplateBinding BorderBrush}"
                Focusable="False">
          <Grid KeyboardNavigation.TabNavigation="Local">
            <Grid.Background>
              <SolidColorBrush Color="{DynamicResource ControlLightColor}" />
            </Grid.Background>
            <Grid.RowDefinitions>
              <RowDefinition Height="Auto" />
              <RowDefinition Height="*" />
              <RowDefinition Height="Auto" />
            </Grid.RowDefinitions>
            <ToolBar ToolBarTray.IsLocked="True"
                     KeyboardNavigation.TabNavigation="Continue">
              <Button Command="NavigationCommands.IncreaseZoom"

                      Content="Zoom In" />
              <Button Command="NavigationCommands.DecreaseZoom"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      Content="Zoom Out" />
              <Separator />
              <!--
              <Button Command="NavigationCommands.Zoom"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      CommandParameter="100.0"
                      Content="Actual Size" />
              -->
              <Button Command="DocumentViewer.FitToWidthCommand"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      Content="Fit to Width" />
              <Button Command="DocumentViewer.FitToMaxPagesAcrossCommand"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      CommandParameter="1"
                      Content="Whole Page" />
              <Button Command="DocumentViewer.FitToMaxPagesAcrossCommand"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      CommandParameter="2"
                      Content="Two Pages" />
            </ToolBar>
            <ScrollViewer Grid.Row="1"
                          CanContentScroll="true"
                          HorizontalScrollBarVisibility="Auto"
                          x:Name="PART_ContentHost"
                          IsTabStop="true">
              <ScrollViewer.Background>
                <LinearGradientBrush EndPoint="0.5,1"
                                     StartPoint="0.5,0">
                  <GradientStop Color="{DynamicResource ControlLightColor}"
                                Offset="0" />
                  <GradientStop Color="{DynamicResource ControlMediumColor}"
                                Offset="1" />
                </LinearGradientBrush>
              </ScrollViewer.Background>
            </ScrollViewer>
            <ContentControl Grid.Row="2"
                            x:Name="PART_FindToolBarHost"/>
          </Grid>
        </Border>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

Dies ist dem verknüpften Beispiel sehr ähnlich, aber ich habe die Befehlsschaltflächen für Druck und Kopieren entfernt. Ich möchte nicht, dass die Benutzer diese Schaltflächen verwenden können.

Ich musste auch das kommentieren Zoom Befehl, die IDE beschwerte sich, dass dies kein gültiger Befehl sei, Bonus -Stimmen für die Antwort auf dieses Problem.

Dies alles funktioniert, aber nach der Vorlagen bekomme ich die Bilder nicht mehr auf den Schaltflächen der Werkzeugleiste, nur den Text, in dem ich angegeben habe, in dem ich angegeben habe Content. Meine Frage lautet also: "Kann ich binden, um Inhalte aus den im Vorlagen verschachtelten Kontrollen zu verwenden?"

Answer 1

Hier ist, was ich bekam, als ich Mischung verwendet habe, um die Vorlage für den DocumentViewer zu extrahieren und zu bearbeiten. Ich habe die beiden Tasten, die Sie erwähnt, kommentiert.

In Bezug auf die Zoom -Befehle könnte es sich möglicherweise über ungültige Befehle beschwert haben, da Ihnen ein Namespace -Import für System.Windows.dokumente fehlte.
